The shear mechanical properties of natural rock fracture play a vital role in resolving complex geotechnical engineering issues. Existing two-dimensional (2D) fracture models fail to capture spatial asperity distribution, while natural three-dimensional (3D) fractures are too random for systematic analysis. To address...
Brazilian tests on limestone with weak interlayers (thickness 0.1–1.35 mm) were performed using RMT and 3D scanning. Results show that BTS decreases nonlinearly with increasing thickness and exhibits a complex angle dependence: fracture length and roughness first rise then peak at 30°, while microscopic features of r...
Bedding planes and natural fractures are key factors controlling the anisotropic mechanical properties of shale reservoirs, exerting a critical influence on underground engineering. However, their shear deformation and fracture evolution mechanisms remain poorly understood. In this study, synthetic shales containing be...
The brittle–ductile transition depth is a key parameter for understanding material removal mechanisms and achieving damage-free surfaces in the machining of brittle single crystals. However, existing predictive models often neglect crystallographic anisotropy and the scale-dependent effects associated with the tool e...
Understanding the mechanical behavior of cemented granular materials under multiaxial stress conditions is essential for the safe and efficient design of filtered tailings disposal systems, yet their anisotropic response remains insufficiently characterized. This study examines the strength anisotropy of iron ore t...
